Verdict
The clearest difference is in-app purchases: US Muscle at none against Internal Combustion Engine ICE's 1. US Muscle also leads on ads (none vs shown) and iOS requirement (9.0 vs 13.0). Internal Combustion Engine ICE's advantage is update cadence (every 2 months vs every 5 months). On price and device support there is nothing between them.
